No 'Access-Control-Allow-Origin' - Node / Apache Port Issue

Question

i\'ve created a small API using Node/Express and trying to pull data using Angularjs but as my html page is running under apache on localhost:8888 and node API is listen on

Answer 1

The top answer worked fine for me, except that I needed to whitelist more than one domain.

Also, top answer suffers from the fact that OPTIONS request isn't handled by middleware and you don't get it automatically.

I store whitelisted domains as allowed_origins in Express configuration and put the correct domain according to origin header since Access-Control-Allow-Origin doesn't allow specifying more than one domain.

Here's what I ended up with:

var _ = require('underscore');

function allowCrossDomain(req, res, next) {
  res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');

  var origin = req.headers.origin;
  if (_.contains(app.get('allowed_origins'), origin)) {
    res.setHeader('Access-Control-Allow-Origin', origin);
  }

  if (req.method === 'OPTIONS') {
    res.send(200);
  } else {
    next();
  }
}

app.configure(function () {
  app.use(express.logger());
  app.use(express.bodyParser());
  app.use(allowCrossDomain);
});
